other unit sign

84S, 84T and is formed colour table C, M in the position, the Y relative position with respect to colour table K with the image that calculates at colour table C, M, Y.

In step S5, position performance image composer 72 uses the relative position that calculates at step S4, generates position represent images 104 (see figure 6)s.To describe subsequently and make position represent images 104 visual concrete forms.

In step S6, display controller 54 control display unit 56 display window W (comprising result screen 100).Before display window W, screen maker 74 generates the video data of the result screen 100 that comprises position represent images 104, and supplies the video data that is generated to display controller 54.

As shown in Figure 6, result screen 100 comprise simulation as the position represent images 104 that generates from the analog image 102 of the being seen chart 30c of planimetric map, by position performance image composer 72, the button 106 that has speech " pattern changes " with have the button 108 that speech " is closed ".If click the Close button 108, window W is closed so, that is, hide.

Analog image 102 is made up of with nine circular image 112 of the relevant position of expression registration mark 82 rectangular image 110 of the shape of representing paper 80 (seeing Fig. 4 A).

As shown in Figure 6, of the upper left corner who is positioned at rectangular image 110 in the circular image 112 illustrates with hachure, and it is selected that expression is positioned at the circular image 112 of " upper left " position.Position represent images 104 makes that now the degree of the misregistration that is positioned at " upper left " position of choosing is visual.

Position represent images 104 comprises the cruciform line 114 of expression two-dimensional position coordinate, three arrow plots round wire 118,120 (image of band scale) as 116c, 116m, 116y and two concentric band scales.Cruciform line 114 has the point of crossing, center 122 that the image of representing colour table K forms the position.Arrow plot is represented colour table C, M, the Y corresponding relative position with respect to colour table K as 116c, 116m, 116y.In other words, position represent images 104 shows the degree of misregistration by the vector of corresponding terminal point that has the image that is in colour table K and form the common starting point of position (point of crossing 122) and be in the relative position of colour table C, M, Y.Thereby just can grasp the relativity shift of colour table more intuitively based on this vectorial size and direction the operator of viewing location represent images 104.Further, by the position of relatively more vectorial starting point, the operator can also grasp some colour tables except that colour table K, for example, and the relative position between colour table C and the M.

If show arrow plot respectively as 116c, 116m, 116y with the color corresponding to the colour table that will actually be used for forming image, the operator can identify and discern the skew of colour table more easily so.The trend that refers to color corresponding to the color of colour table is identical, and for example, in various color systems, the saturation degree of color is identical or approaching.

Near scale mark 118 position display numeral " 50 ", and near the position display numeral " 100 " scale mark 120.These numerals are corresponding to the physical size of the relative position that shows with long measure " μ m ".The operator can be based on the actual shifts that can grasp colour table as some end and the relation a glance of the position between the scale mark 118,120 of 116c, 116m, 116y at arrow plot.Position represent images 104 can comprise explicit or implicitly represent the particular indicators that the maximum of misregistration can the permission level.In Fig. 6, represent that as the circular scale mark that shows 120 of outermost the maximum of misregistrations can allow level.

In response to the clicking operation of " pattern change " button 106, new position represent images 132 (see figure 7)s different on position performance image composer 72 generation forms with position represent images 104.Screen maker 74 generates the video data of the result screen 130 that comprises position represent images 132, and supplies the video data that is generated to display controller 54.Current then on display unit 56 result displayed screen 100 become new result screen 130.

As shown in Figure 7, result screen 130 comprise the position represent images that generates by position performance image composer 72 132, two radio buttons 134, three check boxes 136, the button 106 that has a speech " pattern changes " with have the button 108 that speech " is closed ".In response to the clicking operation of " pattern change " button 106, window W turns back to result screen shown in Figure 6 100 from result screen 130.

Position represent images 132 is made up of eight circular image 142 of the relevant position of the two field picture 140 of the two field picture 138 (being represented by thick line) of the rectangular image 110 of the shape of representing paper 80 (seeing Fig. 4 A), color K, color C and the registration mark 82 of expression except that centrally aligned sign 82.The image of two field picture 138 expression colour table K forms the profile of position.Two field picture 138 representative is similar to the perfect rectangular frame of the rectangular shape of rectangular image 110, and is disposed in the rectangular image 110 with the direction identical with rectangular image 110.

The image of two field picture 140 expression colour table C forms the profile of position, and it forms the profile of position corresponding to the image of colour table K.If the image of colour table C forms the position and is twisted, the rectangular frame of slight distortion is compared in two field picture 140 representatives with desirable rectangular shape so.Therefore, position represent images 132 forms the frame of position by the image of represent colour table K and represent colour table C, M, the Y frame with respect to the image formation position of the image formation position of colour table K, shows the degree of misregistration.Thereby the operator can grasp the relativity shift of colour table on whole paper 80 easily based on the crossing angle of frame, corner location etc.

Because actual skew maximum reaches about 1mm, so the operator is difficult in the image shift on the recognition screen visually, even generate position represent images 132 with the specification ratio suitable with the actual specification of chart 30c.Therefore, can give prominence to or emphasize the relative position of colour table by the image processing means that amplifies or dwindle the image detail of circular image 142.According to this image processing means, position performance image composer 72 generates position represent images 132, wherein with given area (circular image 142) on the different dimensional ratios display frame (two field picture 138,140) and the remaining area on the frame, thereby allowing the operator to grasp is simultaneously not only also having on whole paper 80 in interested eight districts, that is the relativeness between the skew of the colour table of circular image 142.Further, the operator can specify in the image magnification ratio of expecting in circular image 142 zones by click the icon 144 that shows below position represent images 132.

If the operator selects the radio button 134 of indication " opening (ON) " and " closing (OFF) ", show and do not show circular image 142 so respectively.If the operator chooses or do not choose the check box 136 of indication " colour table C ", " colour table M ", " colour table Y ", so independently and optionally show or do not show the two field picture 140 of the colour table that will be estimated, that is the two field picture 140 of the colour table except that colour table K.

In step S7, whether the aligning of operator's decision chart 30c is in admissible scope.If operator's decision chart 30c is aligned in the admissible scope, the operator uses the actual printing process of offset press 32 beginnings so.If the aligning of operator's decision chart 30c is not in admissible scope, control forwards step S8 to so.

In step S8, the operator is by raising whole colour table with reference to the image information that is obtained by image evaluation apparatus 36 in the position.After the position adjustment was finished, control turned back to step S1, and repeating step S1 to S8 among the aligning of chart 30c falls into admissible scope.

As mentioned above, the controller 50 of image evaluation apparatus 36 comprises: relative position counter 70, be used for based on the positional information of the known registration mark 82 that is formed by colour table (colour table C, M, Y, K) and in fact be formed the positional information of the registration mark 82 of image on paper 80, the image that calculates the colour table (colour table K) in a plurality of colour tables forms the two-dimentional relative position between the image formation position of position and other colour tables (colour table C, M, Y); And position performance image composer 72, be used to generate position represent images 104,132, the relative position that position represent images 104,132 is calculated with the representative of two-dimensional position coordinate.Which colour table the operator can understand intuitively is displaced to any degree along which direction, and therefore can grasp the degree of misregistration at a glance.
